Item 21 - Letter from James Challis

Cambridge Observatory - Accepts on behalf of the observatory WW's gift of 'the self-registering magnetic apparatus'. If the Senate authorises the expenditure for another magnetic building he sees no problem in making the observations. Since the instrument is self-registering there is no need for an additional assistant. Cost of publishing the observations could be taken from that allotted to the astronomical ones. It is a shame the observations could not be taken from Lowestoft - the most eastern point in England.
